We look at the division of 8613871 by 80 
Our goal is to divide 8613871 by 80.

Step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 80

Step 2:
86 divided by 80 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 86, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 80

Moving on to step 3:
The number 80 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 80

Advancing to step 4:
If we divide 613 by 80, we get 7 and a remainder of 53.
The next digit of our result is 7. 
Result so far: 107.0
Deduct 560 from 613 and we're left with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 80

Step 5:
80 goes into 538 6 times with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 1076.0
Subtract 480 from 538 to get 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 80

On to step 6:
587 divided by 80 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 10767.0
The remainder is 27 after subtracting 560 from 587.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 80

Let's proceed to step 7:
80 can be fit into 271 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 107673.0
If we subtract 240 from 271, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
The number 80 fits into 310 3 times, leaving a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 107673.3
The remainder is 70 after subtracting 240 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 107673.38
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 107673.387
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 107673.3875
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 107673.3875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 107673.3875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 107673.3875 with a balance of 0.0.
